Boeing X-32

The Boeing X -32 is a technology demonstrator, who competed in the Joint Strike Fighter program against the Lockheed Martin X-35 technology demonstrator.


The requirements for the JSF ( Joint Strike Fighter ) originated in the Joint Advanced Strike Technology program. The X -32 was up against developed by Lockheed Martin X-35. On 26 October 2001, it was then decided that the construction contract is for the future Joint Strike Fighter Lockheed Martin, after which the development has been discontinued.

The design of the X -32 was relatively unusual, especially in comparison to more conventional X -35, and had a large delta-shaped wing which was very thick and therefore stable and could accommodate over 8,000 kg of fuel. Subsequent drafts envisaged a more conventional combination of swept wings, but still be in one piece, and elevators at the rear. The body hangs like a front and rear open box under the wing - the form was copied at penguins. Is the square air intake for the engine, which is relatively far forward mounted in the fuselage at the front opening. The side of the aircraft and engine bay located at the front and the avionics in the central region, the two weapons bays, where there is space for each one JDAM and AIM -120 AMRAAM, a. The main landing gear is retracted into the wings, the nose landing gear under the air intake. The aircraft should have stealth characteristics, but produced relatively low, which was achieved by this unusual design.

The engine used is a Pratt & Whitney JSF119 -614, a modified version of the F119 F- 22nd The rectangular nozzle can be closed for short and vertical landing. The complete thrust is then deflected by two placed at the focus Movable nozzle down. For stabilization, several control nozzles are located in the bow, stern and wings.

We have designed three versions of the X -32. The basic model for the U.S. Air Force, a version for the U.S. Navy with reinforced suspension, larger wings and tail hook and the version for the U.S. Marines, which briefly start and can land vertically ( STOVL version).

Two airworthy machines were built by Boeing. First flight of the demonstrator X -32A took place at Edwards Air Force Base on 18 September 2000 from Palmdale. The X - 32B demonstrated the short takeoff and vertical landing capabilities, had its maiden flight on 29 March 2001. Had you from the X -32A lesser extent. The first transition in the hover flight took place on 24 June 2001. Was first vertical landing on 27 June 2001 at the Patuxent River Naval Air Station.

The X -32 is smaller, faster and more maneuverable than the X - 35, but could result in less payload,. The flight tests of the X - 32B were carried out for example with a shortened air intake in order to save weight. The cockpit had high-resolution displays to control many functions could be controlled by voice commands or Displayeinspiegelungen in the helmet of the pilot.

The X -32A is currently in the National Museum of the United States Air Force ( Dayton, Ohio) and is being restored. She was commissioned on 3 February 2001 after more than 60 missions and 50 hours off duty. The X - 32B had completed up to its decommissioning at July 28, 2001 78 test missions and 43 flight hours. Since 31 March 2005, the X - 32B is on display alongside the X -35C at the Patuxent River Naval Air Museum ( Maryland).
